Abstract: PURPOSE: A method for an outer lace integral stator of an automatic mission for a vehicle is provided to endure a friction force as the torque change transferred from an engine by changing the quality of the outer lace and integrally casting. CONSTITUTION: A preform(10) is produced according to the position shape to reinforce by using a ceramic reinforcing material containing an aluminium complex material. After the preform is installed in a metal mold(20), molten steel of 700 to 800°C is put in the mold. The molten steel is pressured by using the metal mold, and a complete product is taken out by separating the metal mold so that the outer lace integral stator is produced.

Abstract: PURPOSE: A method for producing a diesel engine piston is provided to save a producing cost by producing a complex material diesel engine piston for reinforcing a top ring groove by using a horizontal squeeze molder and to improve the durability of the piston. CONSTITUTION: A diesel piston(50) is formed in a cylindrical shape to form a side face and a pin-boss unit(51), and a pre-form(55) is formed to reinforce a top ring groove(52) on a lower end. Then, molten metal is quickly filled up into a cavity by moving the plunger at a fast speed after manipulating a handle and a valve of regulating a high speed injection speed at a point that molten metal in an injection sleeve moves toward the cavity after passing through a hole since a pressurizing plunger continuously forwards. Herein, the molten metal is contacted with the pre-form(55), and the injection pressure is kept for 30 to 120 seconds waiting for being solidified. Thereby, if the molten metal is integrally solidified, a mold on a mobile side is separated from a mold on a fixed side, and at the same time, an upper slide core is separated from a lower slide core. Then the solidified diesel piston is separated by using a compression rod and plate of a compression cylinder.

Abstract translation: 目的：提供一种生产柴油发动机活塞的方法，通过使用水平挤压成型机制造用于加强顶环槽的复合材料柴油发动机活塞并提高活塞的耐久性来节省生产成本。 构成：柴油活塞（50）形成为圆筒形状以形成侧面和销 - 凸台单元（51），并且形成预成型件（55）以在顶部环形槽（52）上加强 下端 然后，通过在操纵手柄之后以快速的速度移动柱塞，将熔融金属快速填充到空腔中，并且在通过注射套筒中的熔融金属朝着空腔移动的点调节高速注射速度的阀门 一个加压柱塞连续向前的孔。 这里，熔融金属与预成型体（55）接触，注射压力保持30〜120秒等待固化。 由此，如果熔融金属整体固化，则移动侧的模具与固定侧的模具分离，同时将上滑动芯体与下滑动芯体分离。 然后使用压缩缸的压缩杆和板分离固化的柴油活塞。

Abstract: 본 발명은 용탕단조장치를 이용한 디젤 피스톤의 제조방법에 관한 것으로, 별도로 제작된 프리 폼과 솔트 코어를 각 다이가 조합되어 이루어진 자리면과 하부금형의 상부에 설치하여 복합재질 용탕을 주입하고, 펀치로 용탕을 가압함에 따라 과다 주입된 용탕의 다이 외부로 배출가능하게 함으로써, 솔트 코어가 없는 단순 복합재료로 이루어진 피스톤 뿐만 아니라 솔트 코어의 위치를 달리하는 피스톤을 쉽게 재작할 수 있는 용탕단조장치를 이용한 디젤 피스톤의 제조방법을 제공하는데 있다.
